That is one catch. But from what I have read here, http://www.vegasmessageboard.com/forums/showthread.php?t=82489 it is pretty legit. I have to warn you, it is a major timesuck though. I unfortunately have no life now, so I've been doing it. Also in the linked thread, certain betting patterns are better for earning "loyalty points" than others. Mainly betting 10X line bet on most games until you reach Level 58. Yes, I said Level 58, and that's where I am at right now. It took over 7 weeks of mindlessly auto-spinning and clicking on bonus games when you get them (I usually play "Lucky Birds", it's one of the easier ones to set and forget). And another tip, try to complete building each property at particular times of day. Once you complete a property a permanent clock begins where you can collect game chips or loyalty points from each property. It goes as follows:

So one of the more efficient things you can do is complete all the properties that are 6 hours or less around the same time in the day, so you can collect all of these properties every 12 hours, twice! Why twice? Because when a property is "due" you have the same amount of hours to collect the current amount of chips. So if you build the Aria at 8:30PM for example, you can collect chips or loyalty points 4 times a day: 8:30P, 2:30A, 8:30A, 2:30P. So ideally you start playing the game at 8:25P, so you can collect the 2:30P award, and then 5 minutes later, you'll be able to collect the 8:30P award. And of course correlate building the MGM Grand with the time you are most likely to be playing the game along with your other properties, then you'll be able to easily collect that 2X a day as well.

I currently have 97k in loyalty points which means I could stay 2 nights (Sunday-Thursday) in a Mirage suite that is ~1000 sq. ft. for free (full retail value $700+). Recently, they usually offer rooms at discounted loyalty point rates for specific time frames in the next few weeks. So next Vegas trip, I likely book one of those, and then call CET (who I normally stay with thanks to the "Race to Rewards") to adjust my reservation accordingly. The available rewards are limited and are apparently reset at Midnight PST. So if there is something really popular, you need to get it then. The rate of "rewards" you could earn, I might value them at a few bucks an hour if you use them wisely and can keep the game constantly spinning at 10X line bet.

I've done this for a while. It's legit, but, as other people have said, it's a timesink designed to tempt you to buy chips to play longer.

I basically collect 50k chips from other people's feeds each day and leave spins going at the most efficient chip:point rate, checking every once in a while if it's hung up on a bonus. I also use it as a "teaching tool" for slots: Pretty much the only way you'll ever be able to keep playing is with regular infusions of outside money...

I have spent a good deal of time looking into myVegas. In the beginning, it was mind numbing, so I used a tool that I have to automate playing the Excalibur game. It was a pain because of the high frequency of mini games and having to make a selection. Now, I play for about 15 minutes each day and I almost exclusively play blackjack at 6,000 credits per hand. The reason I cap it at 6,000 is because myVegas limits the accumulation of experience points. Playing in turbo mode at the bet, I can gain 100,000 experience points every 3 or 4 minutes (experience points are good for leveling up). Because the return on blackjack is so high compared to the slot games, they offer experience points at half the rate of the slots and they award loyalty points at about 1/6th the rate of slots.

Also, the less you bet, the higher the accumulation rates per credit wagered.

Playing Bet the Farm at 34 credits per spin requires 4146 credits wagered to gain 10 loyalty points and 4146 experience points. This is the best slot wager in the game, but it will take FOREVER to gain levels when you get higher up.

I have also done the math for 2 of the slot games: Excalibur and NYNY. The return on both of the games is 92% and I suspect that the return on the other slot games is also 92%.

If you are a new player, I recommend joining the group MyVegas Friends on facebook and going to the chip feed link, where you'll be able to collect about 40,000 credits within about 20 minutes of clicking on links.

Wow. I have been tempted to try to deconstruct NYNY, but I have yet to get around to it.

When you have bonus games with differing values of credits available, how are you estimating the probabilities of the differing bonus game boards occur? Record all the bonus games and analyze the data you find? I also know that in NYNY, the lower left moneybag in the "Downtown Bonus" is never a collect. And what is the probability of unlocking the safe in that bonus? It seems greater than one-third to me, so I'm guessing that 2 numbers open the safe, maybe?

All bonus games are pre-determined. Before you ever select a safe number, the game knows whether you are going to open the safe or not. I didn't spend a lot of time collecting bonus info for this game, but in my sample, I opened the safe 35 out of 45 times. To estimate the bonus pay, I just averaged the pay awarded for the 45 bonuses.

For the uptown bonus, I won 35/53 times.

The reason I decided to stop collecting info is because the averages that I got put the game right at 92%, which is what I expected.

I forgot, I also analyzed Lost in Time, and I got a return of about 91.5%. But, in Lost in Time, there are a lot more unknowns, such as how many free games, on average, are awarded for finding the items in the bonus. Also, the time machine numbers at the bottom do not have a 1 in 10 chance of matching. I suspect if I collect more data, I'll find that the return is 92%.
